A specific analysis must be made on a case-by-case basis. If the bleeding is only 5 ml at the brain level, the risk factor is relatively small. As long as it is not in some particularly important functional areas, such as the thalamus or the internal capsule, basically 5 ml of bleeding will not cause obvious clinical symptoms, and there will not be any obvious complications or sequelae, and basically it will improve after active treatment. However, if the brain hemorrhage is in the brainstem or in the cerebellum, it may have very serious consequences, especially in the brainstem and especially in the medulla oblongata of the brainstem. If the hemorrhage is 5 ml, it is very serious and may directly cause the patient’s respiratory and circulatory function to be suspended, leading to death. Therefore, for cerebral hemorrhage, it is important to clarify the location of the hemorrhage, the amount of hemorrhage and whether there is any specific compression of the surrounding blood vessels and nerves, so that it can be clear whether it is serious or not.
